I agree.

Garters are not "snake eaters" but ANY snake is capable of eating a cagemate during a feeding mistake, like 2 snakes eating opposite ends of a food item, and as Wayne said, sometimes the scent lingers for a bit and can still be a risk for sparking that feeding response.

I'm not saying you cant keep them together-it might work fine - but I would be careful, and supervise feeding time very well, or separate them for feeding and leave them separate for a little while after, till their feeding response dies down.

If you do have males and females of different species, my thought is this- if they will inevitebly need separate caging to avoid hybridizing when older, I would consider just holding off for right now and planning for that eventual caging scenario.
